Red grapefruit

One of winter's tastiest gifts, red grapefruit offers vitamin C and lycopene, a cancer-fighting phytochemical found in red plant foods. Look for heavy grapefruit with golden, tight skins and no obvious soft spots; store only a couple of days at room temperature or in a bag in your fridge's vegetable drawer.

For an easy, bright salad dressing, mix one part red-grapefruit juice with one part white balsamic vinegar and two parts fruity olive oil. Season with salt, pepper, and a little Dijon mustard. Drizzle on a salad of thinly shaved fennel, orange sections, and butter lettuce.

Toss grapefruit sections into chicken or shrimp salad with cashews, golden raisins, green onions, parsley, and a light sauce made with mayonnaise and fresh red-grapefruit juice.
